Here is a quick resource for finding and using the Quest Oracle Community Enhancement Tool, which lets you introduce and advocate for JDE improvements and enhancements that can be introduced in future product releases.
If you're paying attention in ORACLE presentations at INFOCUS e.g. you can see "Quest Enhancement Request nnnnnnn" in the footer and this is where they come from.
Even if you don't have one yourself, you should still go there and browse the current ones and prioritize them, as numbers are equally as important!
